- The Western is a film genre defined by the American Film Institute as films which are “set in the American West that [embody] the spirit, the struggle, and the demise of the new frontier.” Generally set in the American frontier between the California Gold Rush of 1849 and the closing of the frontier in 1890, the genre also includes many examples of stories set in locations outside the frontier – including Northern Mexico, the Northwestern United States, Alaska, and Western Canada – as well as stories that take place before 1849 and after 1890. Western films comprise part of the larger Western genre, which encompasses literature, music, television, and plastic arts.

The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. It was formerly considered to be part of a larger Great Rift Valley that extended north to Asia Minor.
